A Research On Electromotive Force Concept In Senior High School Physics Teaching

The physics conception is not only the base, but also an important section of physics. The teaching of physics conception is very important and always a difficulty. Especially the teaching of abstract conception, such as learning and teaching of the conception of electromotive force always confuse teachers and students.On the basis of the constructivism, the instructional design and the concept teaching theory, in this paper, we have a research on the conception and teaching of electromotive force from different angles.This paper focuse on the analysis of the knowledge and the explaination of confusing problems related to the electromotive force after the study on the documents. Through the investigation of last 20 years documents, we study on the compiling of the knowledge related to electromotive force, and compare systematically the different definitions, introduction and the correlation content arrangement way of electromotive force. The main reason caused the obstacle encounted in the learning the conception of electromotive force is summarized by the method of questionnaire investigation and personal interview. Then we give some constructive suggestions.Through the study on the existing instructional design of electromotive force, we conclude the various processes of teaching design and summarize the varieties of the teaching target, the teaching media choice and the teaching method applications, then we provide an instructive and constructive example of instructional design.This paper intends to give the way and thread for high school teachers and students to study the other analogous conceptions.
